Messenger Viber has long ceased to be just a tool for text messages, turning into a multimedia platform that greedily absorbs free space on a smartphone. The constant exchange of photos, high-resolution videos, voice messages and documents leads to the fact that, unbeknownst to the user, the device storage is filled with gigabytes of temporary files. This causes slowdown of the operating system Android, problems with installing new applications and periodic failures in the operation of the messenger itself.
Cleaning accumulated “garbage” is not just a cosmetic procedure, but a necessary measure to maintain the performance of the gadget. In this article, we will analyze in detail all the available methods for freeing up space: from the built-in tools of the app itself to deep cleaning through system settings and file managers. You will learn how to delete unnecessary things without the risk of losing important correspondence or contacts.
Analysis of occupied space
Before taking decisive action and deleting files, you need to conduct a thorough audit and understand what exactly takes up the most space. Modern versions Viber have built-in storage analysis tools that allow you to see the amount of data per specific chats or file types. This helps identify the “heavyweights” - conversations with active video sharing or group chats where hundreds of images are uploaded.
It is important to understand the difference between cache and user data. Cache is temporary files that speed up the loading of frequently visited pages or image previews; deleting them is safe. User data includes message history, contacts and media files that you have saved. Clearing data through system settings will completely reset the application, which will require you to register again.
⚠️ Warning: Before deleting any files, make sure you have an up-to-date backup of important chats, if they are not synchronized with the cloud.
To begin the evaluation, let's go to the settings of the application itself. Go to More → Settings → Memory. Here you'll see the total amount of space taken up and a breakdown by category: images, videos, audio and documents. By clicking on a specific category, you can study the contents in detail and delete unnecessary ones.
- 📸 Images: often take up to 40% of the space, especially if autosaving is enabled in the gallery.
- 🎥 Video: heaviest content, one minute video can weigh 50-100 MB.
- 🎵 Audio: voice messages and music files sent in chats.
- 📄 Documents: PDF, APKs and archives that are often forgotten to be deleted after use.
Regular monitoring of these indicators allows you to keep the situation under control and prevent critical memory overflow.
Using the built-in Viber cleaner
The safest and most convenient way to free up space is to use standard "Memory Cleanup" tool, which the developers have built directly into the application interface. This method is good because it deletes only temporary files and cache, without affecting your correspondence history and account settings. The process is fully automated and does not require deep knowledge of the file system Android.
To start cleaning, open the menu More in the lower right corner of the screen, then select Settings. In the list of options, find the item Memory and click on the button Clear memory (or "Clear cache", depending on the translation version). The system will offer to delete temporary files accumulated over the entire period of using the messenger.
☑️ Check before cleaning
After the process is completed, you will see a message about successful freeing up space. That this method does not delete media files from the chats themselves, it only clears the technical garbage. If, after cleaning, the memory fills up again within a couple of days, then the problem is in the active exchange of “heavy” files, and you need to configure the download settings.
- ✅ Safe for personal data and message history.
- ✅ Does not require superuser rights or connection to a PC.
- ✅ Instant results without the need to reboot devices.
Use this function regularly, for example, once a week, to prevent the cache from growing to gigantic proportions.
Deleting media files through a file manager
For deeper cleaning, when the built-in tools do not help free up enough space, you will have to work with the file system directly. On modern versions Android (starting from version 11), access to folders is limited, but main media files Viber often remain accessible through the standard Explorer or the Files application from Google.
You need to find the folder where the messenger saves received images and videos. The path may look like Internal Storage → Android → media → com.viber.voip → Viber or simply Internal Storage → Viber. Inside you will find folders Images, Video, Audio. This is where copies of all received files are stored.
⚠️ Attention: Deleting files from here through Explorer will delete them from chats forever, it will be impossible to restore them without a backup.
The advantage of this method is that you can sort files by date or size and delete only old or unnecessary ones. For example, you can go to the folder Video, sort files by size and delete the “heaviest” videos that are no longer relevant. This allows you to free up gigabytes of space selectively.
- 🗑️ Allows you to delete files selectively, rather than all at once.
- 📂 Gives access to hidden folders not visible in the gallery.
- ⚡ Works faster when bulk deleting large amounts of data.
After manual cleaning through the file manager, it is recommended to restart the smartphone so that the system correctly recalculates the free space.
Setting up autosave and autoload
The main reason for the rapid filling of memory is the default settings, which allow the application to automatically save all incoming media files to the phone gallery. By changing these settings, you will prevent future problems with running out of space. This is the most effective preventive measure.
Go to Settings → Storage (or Privacy in some versions). Find the item Save to gallery and disable it. Now photos and videos will be displayed inside Viber, but will not be duplicated in the system gallery, taking up double space. It is also useful to disable auto-downloading of media files when using mobile traffic.
Disable autosave for group chats, where memes and cards are often sent, leaving this function enabled only for selected contacts.
Additionally, you can configure history clearing. In the Calls and messages section, find the option Save message history. If you select a time limit (for example, 3 months or 1 year), old messages will be deleted automatically. This is especially true for devices with a small amount of built-in memory.
- 🚫 Disabling autosave saves up to 60% of space in the long run.
- 📉 Limiting message history reduces the load on the database application data.
- 🌐 Disabling downloading over a mobile network saves traffic and space.
After changing the settings, they are applied to all new incoming files, so the result will not be noticeable immediately, but as you actively use the messenger.
Comparison of cleaning methods
The choice of cleaning method depends on your goal: whether you need to quickly free up some space, do a deep clean, or set up the system for the future. Each method has its own advantages and disadvantages that are worth considering. Below is a comparative table of the main methods.
| Method | Data security | Efficiency | Complexity |
|---|---|---|---|
| Built-in cleaning | High | Low (cache only) | Minimum |
| Deleting chats | Low (data is lost) | High | Medium |
| File manager | Medium (risk of error) | Maximum | High |
| Auto-save settings | High | Preventive | Minimum |
As can be seen from the table, a combination of built-in cleaning and correct autosave settings is best suited for regular maintenance. Manual deletion through a file manager should only be used in critical situations, when the memory is full and the phone is working slowly.
Do not forget that deleting correspondence is an irreversible process unless a backup is made. Therefore, before using radical methods, always weigh the value of the information.
Clearing the cache through the Android system settings
If the built-in tools do not work or the application is frozen, you can use the system tools Android. This method allows you to force clear the cache, but requires care not to delete your account data. The path to the settings may differ depending on the smartphone model (Samsung, Xiaomi, Pixel).
Go to Settings phone, find the section Applications (or All applications). Find Viberin the list. Click on it, then select Memory or Storage. Here you will see two buttons: Clear cache and Clear data (or Reset).
Press only Clear cache. This operation will delete temporary files, thumbnails and logs, but will save your messages and login settings. If you press Clear data, the application will return to the state immediately after installation, and you will have to re-enter the phone number and verification code.
What to do if the "Clear cache" button is inactive?
Sometimes the system blocks clearing if the application is running. Try to force stop Viber in the same settings menu, and then the button will become active.
After clearing the cache through system settings, it is recommended to completely close the application. and start it again. The first opening may take a little longer, since Viber will re-form the cache.
- 🔧 Helps with application errors and freezes.
- 📱 Available on all devices without installing third-party software.
- ⚠️ Requires care not to confuse the buttons.
Use this method if standard cleaning within the application does not give results or the button is missing.
Specifics of working on different versions of Android
The cleaning procedure may differ depending on the operating version systems and the manufacturer's shell. On older versions (up to 10), access to the file system was easier, and files were often located in the root of the folder. On new versions (11, 12, 13, 14), strict application isolation was introduced, and access to the folder may be possible. limited. Android (before 10th) access to the file system was easier, and files were often located in the root of the folder Viber. On new versions (11, 12, 13, 14), strict application isolation has been introduced, and access to the folder Android/media may be limited.
Owners of smartphones Samsung with a shell One UI should pay attention to the built-in application "Device Maintenance". It often has a memory analysis function that automatically finds large files in Viber and offers to delete them. This is a convenient standard tool that does not require third-party ones. downloads.
⚠️ Attention: The settings interface may change with application updates. If you do not find the described item, use the search inside the phone or application settings.
On devices Xiaomi (MIUI) and POCO aggressive memory cleaning may cause Viber stops receiving messages in the background. After clearing the cache, check your battery settings and allow the application to autostart so as not to lose the functionality of the messenger.
- 📱 Android 10 and below: direct access to files in the root memory.
- 🔒 Android 11+: access through the system explorer is limited to the media folder.
- 🛡️ Shells: Samsung and Xiaomi have their own optimization utilities.
Always consider the features of your device model when choosing a cleaning method.
Third-party applications for cleaning
There are many cleaner applications (Clean Master, CCleaner, Files by Googlethat promise to free up space with one click. They can be useful for finding duplicate files or residual garbage from deleted apps, but Viber you need to be careful. Often these apps offer to delete the "cache", which is actually important session data.
The most secure third-party solution is the application Files by Google. It has a "Cleaning" tab, where a smart algorithm suggests deleting old screenshots, blurry photos and large video files, including from messenger folders. It does not go into the system files of the application, but only works with user content.
Third-party cleaners are useful. to find duplicates, but the built-in tools of Android and Viber are safer for working with the cache of the application itself.
Avoid installing dubious applications with names like "Viber Cleaner" from unknown developers. They may request excessive permissions, read your correspondence, or show intrusive ads. Standard tools are usually enough to maintain order.
- 🧹 Files by Google: safely finds large files and duplicates.
- ⚠️ Risks: Some cleaners can damage the message database.
- 🔍 Search for duplicates: The only function where third-party software is truly irreplaceable.
Use third-party software only as an addition to manual cleaning, and not as a main means of maintenance.
Is it possible to clear Viber's memory without deleting correspondence?
Yes, you can. Use the built-in "Clear memory" function in the settings of the application itself or the "Clear cache" button in the Android system settings. These actions delete temporary files, but save the message history.
Where do photos go after clearing the cache?
Photos from chats remain visible in correspondence, but their previews (thumbnails) can be reloaded when opened. If you deleted files through the file manager, they will disappear from chats forever.
Why does Viber quickly fill up the memory again?
Most likely, you have autosave in the gallery and autoloading of media enabled. Disable these functions in Viber settings so that files are not duplicated and downloaded automatically.
Is it safe to delete the Viber folder in the file manager?
You can only delete the contents of the Images, Video, Audio folders. Do not delete the database folder itself or the configuration files, otherwise the application may stop working correctly.
